Automated document collection, AI filing, and DMS sync for modern accounting firms.

Automated document collection, AI filing, and DMS sync for modern accounting firms. Technical Deep-Dive AldenSync + Karbon: A technical integration walkthrough. This isn't a marketing overview. This is the technical walkthrough its implementation team uses internally, now published for firms evaluating how deeply AldenSync connects to Karbon. Authentication & connection setup. AldenSync connects to Karbon via OAuth 2.0 with PKCE. During onboarding, an admin authorizes AldenSync with read/write access to Contacts, Work Items, and Client Tasks. Aldensync request the minimum scopes needed: - `contacts:read` - pull client names, emails, entity details - `work:read` / `work:write` - read engagement status, update task completion - `tasks:read` / `tasks:write` - create document request tasks, mark as complete - `notes:write` - post automated status updates to engagement timelines Aldensync never request access to Karbon's financial data, budgets, or team management features. Principle of least privilege. Engagement mapping. The first step after connection is mapping your Karbon Work Items to AldenSync engagements. Aldensync support three mapping strategies: - Automatic by client name + work type - AldenSync matches Karbon work items to engagements using client name and engagement type (e.g., '1040 Individual Tax Return'). Works for 90%+ of firms. - Template-based - you define a mapping template: 'All Karbon work items of type X map to AldenSync engagement template Y.' Useful for firms with custom work types. - Manual override - for edge cases, you can manually link specific Karbon work items to specific AldenSync engagements. Real-Time task sync. This is where it gets interesting. When a client uploads a document through the AldenSync portal: 1. AldenSync's AI classifies the document (W-2, 1099, K-1, etc.) 2. The document is filed in your DMS with your naming convention 3. AldenSync sends a webhook to its Karbon sync service 4. The sync service identifies the corresponding Karbon Work Item 5. The matching Client Task in Karbon is marked as complete 6. A note is posted to the Work Item timeline: 'W-2 received and filed via AldenSync' This happens in under 3 seconds from upload to Karbon update. No polling - Aldensync use event-driven architecture with webhook delivery. Handling multi-entity engagements. Firms with clients that have multiple entities (e.g., an individual with an S-Corp and a rental LLC) need documents routed to the correct engagement. Aldensync handle this by: - Matching the entity name on the uploaded document to the Karbon Work Item's client entity - If ambiguous, routing to a review queue where a staff member confirms the correct engagement (takes ~5 seconds) - Learning from these corrections - after 3-5 manual confirmations for a client, the system handles it automatically Error handling & edge cases. What happens when things go wrong: - Karbon API timeout: Aldensync queue the update and retry with exponential backoff (30s, 60s, 120s). If Karbon is down for extended periods, updates batch and apply when the API recovers. No data loss. - Duplicate work items: If multiple Karbon Work Items match a single document, Aldensync flag it for manual routing rather than guessing. - Deleted work items: If a Karbon Work Item is deleted after a document was linked, Aldensync notify the firm admin and re-queue the document for manual assignment. What Aldensync don't do. Aldensync intentionally don't: - Create new Work Items in Karbon (your workflow, your creation process) - Modify work item status beyond task completion (Aldensync update tasks, not engagement stages, unless you configure it) - Sync backward (if you manually mark a task complete in Karbon, Aldensync don't retroactively look for the document) This keeps the integration predictable and debuggable. Performance at scale. Its largest Karbon-connected firm processes 1,200 engagements per season with 15,000+ documents. Average sync latency is 2.4 seconds. Aldensync has had zero data mismatches in the last 12 months across all Karbon-connected firms. Want to see this in action?
